Treatment of Anxiety Attack
For an acute anxiety attack, initiate slow, deep breathing exercises immediately (6-10 breaths per minute) while simultaneously assessing whether this represents an isolated panic attack or part of an underlying anxiety disorder requiring ongoing pharmacological and psychological treatment. 1, 2
Immediate Management of Acute Anxiety Attack
Breathing Techniques (First-Line Acute Intervention)
- Implement slow, deep breathing at a rate of 6-10 breaths per minute for at least 5 minutes to rapidly reduce anxiety symptoms and restore vagal tone. 1, 2, 3
- Slow breathing significantly increases parasympathetic activity (measured by HF power on HRV) and reduces state anxiety within a single session, with effects particularly pronounced in older adults. 3
- Avoid fast-only breathing patterns, as these are ineffective and may worsen symptoms. 2
- Respiratory control techniques work by reversing hyperventilation-induced panic symptoms and should include reattribution training (explaining that symptoms result from overbreathing rather than catastrophic causes). 4
Acute Pharmacological Management (When Breathing Techniques Insufficient)
- Alprazolam 0.25-0.5 mg can be administered for immediate relief of severe anxiety attacks, though this should not be the primary long-term strategy. 5
- Alprazolam provides rapid anxiolytic effects but carries significant risks of dependence, particularly with doses above 4 mg/day and prolonged use. 5
- Benzodiazepines should be reserved for acute situations where breathing techniques are insufficient and while establishing longer-term treatment. 6
Ongoing Treatment for Anxiety Disorders
First-Line Pharmacological Treatment
- Initiate an SSRI (escitalopram 5-10 mg daily or sertraline 25-50 mg daily) as first-line pharmacological treatment, titrating slowly over 1-2 weeks to minimize initial activation symptoms. 7, 8
- Escitalopram and sertraline are preferred over other SSRIs due to superior efficacy, favorable side effect profiles, and lower discontinuation syndrome risk. 7, 8
- For fluoxetine specifically, start at 5-10 mg daily and increase by 5-10 mg every 1-2 weeks, targeting 20-40 mg daily by weeks 4-6, with maximal benefit expected by week 12. 9, 7
- Venlafaxine extended-release (75-225 mg/day) is an effective alternative SNRI, though it requires blood pressure monitoring due to hypertension risk. 7, 8
Critical Pitfall: Avoid paroxetine as a first-line agent due to higher discontinuation syndrome risk and potentially increased suicidal thinking compared to other SSRIs. 8
Response Timeline and Monitoring
- Assess treatment response at 2 weeks (statistically significant improvement), 6 weeks (clinically significant improvement), and 12 weeks (maximal benefit) using standardized anxiety scales. 6, 7
- If inadequate response after 8 weeks at therapeutic doses, switch to a different SSRI or SNRI rather than continuing ineffective treatment. 6, 7
- Monitor for common side effects including nausea, sexual dysfunction, headache, insomnia, and activation symptoms, which typically emerge within the first few weeks. 7, 8
Psychological Treatment (Essential Component)
- Initiate individual cognitive behavioral therapy (CBT) targeting anxiety-specific patterns, ideally in combination with pharmacotherapy for optimal outcomes. 6, 7, 8
- Individual CBT is superior to group therapy for anxiety disorders, with large effect sizes (Hedges g = 1.01 for GAD). 7
- CBT should include 12-20 structured sessions incorporating psychoeducation, cognitive restructuring, relaxation techniques, and exposure when appropriate. 7
- Combination treatment (SSRI + CBT) is superior to monotherapy alone for most patients. 8
Treatment Algorithm for Inadequate Response
- Week 0-2: Start SSRI at low dose + breathing techniques + consider CBT referral 7, 8
- Week 4: Assess response; if inadequate, increase SSRI dose 6, 7
- Week 8: If still inadequate response despite therapeutic doses, switch to different SSRI/SNRI 6, 7
- Week 12: If no improvement with second agent, consider adding CBT (if not already implemented) or switching to pregabalin/gabapentin as second-line agents 7
Special Populations and Considerations
- For patients with comorbid depression and anxiety, prioritize treatment of depressive symptoms first, or use a unified protocol combining CBT for both conditions. 6
- Duloxetine (60-120 mg/day) offers additional benefits for patients with comorbid pain conditions. 7
- Provide culturally informed and linguistically appropriate education about anxiety symptoms, treatment options, and warning signs of worsening. 6
Critical Pitfall: Avoid tricyclic antidepressants due to unfavorable risk-benefit profile, particularly cardiac toxicity. 7
Discontinuation Strategy
- Taper SSRIs gradually (decrease by no more than 25-50% every 1-2 weeks) to avoid discontinuation syndrome, particularly with shorter half-life agents like sertraline and paroxetine. 8, 5
- Discontinuation symptoms include dizziness, fatigue, headaches, nausea, insomnia, and rebound anxiety. 8
- Fluoxetine's longer half-life minimizes discontinuation risk and may be beneficial for patients with adherence concerns. 7, 9
